50 THE entomologist's RECORD. 



Edwards, and others, will finish the work, but necessarily there will 

 be some delay. In this connection we would like to point out that the 

 account of Pob/oiiniiatus icartis being practically completed in the 

 parts already issued, there only remain the two species of Lycaenids, 

 Aricia astraiche {ai/cstis) and Lycaena arinn to be dealt with. Mr. 

 Tutt had proposed to include also Nenieohiiifi liicina in this volume, 

 provided space permitted. We should therefore be pleased to 

 obtain all and any material or information of any kind with 

 regard to these species, that we may hand it over to be dealt with by 

 the collaborateurs. We need particulars in detail of Gynandromorphs, 

 Teratological examples, Pathological examples (see Brit. Lep. vol. x., 

 p. 122, 1\ icarus), Varieties in size, in seasonal form, in eoloiir, in 

 shape, in local form, giving full particulars whether ^ or J , upper 

 or underside, etc. Especially is material needed from outlying parts 

 of the British Islands, and for comparison from the whole of the 

 Palfearctic region, wherever the two species may be obtainable. 

 Imaginal and larval habits in different localities vary with circum- 

 stances, and want recording for assimilation and record in the life- 

 history. The lists of localities and dates of capture are most useful, 

 and the more one has of them the better can the distribution of the 

 species be ascertained both geographical and seasonal. For all these 

 items of information we shall be most grateful. 



SOCIETIES. 



Entomological Society of London. — The annual meeting of 

 this Society was held on Wednesday, January 18th, at 11, 

 Chandos Street, Cavendish Square, when the Officers and Council for 

 the forthcoming session, 1911-12, were elected. Owing, however, to 

 the death of Mr. J. W. Tutt, the President-nominate, no successor to 

 the outgoing President, Dr. F. A. Dixey, M.A., M.D., F.E.S., was 

 chosen, and a special general meeting will be held later in the year for 

 that purpose. MeanAvhile the following Fellows were elected to act as 

 officers and members of the council: — Treasurer, Mr. A. H. Jones; 

 Secretaries, Com. J. J. Walker, M.A., R.N., F.L.S., and (in place of 

 Mr. H. Rowland-Brown, M.A., who resigns after eleven years' service) 

 the Rev. G. Wheeler, M.A., F.Z.S. ; Librarian, Mr. G. C. Champion, 

 F.Z.S. ; other Members of the Council : Mr. R. Adkin, Mr. G. T. 

 Bethune-Baker, F.Z.S., Professor T. Hudson-Beare, B.Sc, F.R.S.E., 

 Dr. M. Burr, D.Sc, F.L.S., F.Z.S., Dr. F. A. Dixey, M.A., M.D., 

 F.R.S., Mr. H. St. J. Donisthorpe, F.Z.S., Mr. J. H. Durrant, 

 Professor Selwyn Image, M.A., Dr. K. Jordan, Ph.D., Mr. A. Sich, 

 Mr. J. R. le B. Tomlin, M.A., and Mr. H. J. Turner. The President, 

 in the course of his Address, after referring to the losses by death 

 sustained during the preceding year, went on to speak of various 

 events of special interest to entomologists, among these being the 

 appointment of Professor Meldola, F.R.S., as Herbert Spencer Lecturer 

 and Mr. Selwyn Image as Slade Professor of Fine Art at Oxford ; the 

 award of the Royal Society's Darwin Medal to Mr. Roland Trimen, 

 F.R.S. ; and the meeting of the first International Congress of 

 Entomology at Brussels. He then proceeded to deal with certain 

 problems of general biology on which special light had been thrown 

 by entomological study, notably the demonstration that permanent 

 races, differing from the parent stock, could be produced by artificial 

 interference with the germ-plasm. This had been surmised from
